Title: Automatic clamping arrangement for liquid treatment apparatus
Inventor: NEVETT ROY
IPC: A47L15/26
Filed: 1983-06-21
Abstract: Rotor 102 which forms part of a liquid treatment plant, e.g. for washing used food containers, is indexed, for example, by a Geneva mechanism 14, 15. In loading position A, each compartment 13 is loaded and the free end of a respective pivoted member 31, 55 which defines the lower limit of the load- receiving space is raised, e.g. by pulley mechanism 36, 38, 40, 52, to clamp the load against the upper limit of the same compartment 13. Retainer means, e.g. ratchet 54 and stop member 57, 58 hold the free end of the pivoted member in this position as the compartment 13 passes through liquid treatment positions B and C. At the unloading position D, the retainer means is released when the free end is raised, e.g. by a corresponding pulley mechanism 37, 39, 41, 51. In an alternative embodiment the free end of respective pivoted members may define the upper limit of the respective load-receiving spaces at the loading position A. The clamping arrangement permits retention of loads of various shapes and sizes as they pass through the treatment positions. <IMAGE>

Title: Chute for conveying objects e.g. fruit under gravity
Inventor: MOORE ANDREW THOMAS
IPC: B65G11/10
Filed: 1983-12-02
Abstract: A chute (10) for conveying objects (24) (e.g. fruit) in a controlled manner under gravity from an elevated position to a lower, delivery position, comprises a receptacle (14) for receiving such objects through an entry opening (22) at the top thereof and admitting them through an exit opening into a chute tube (34) secured around a nozzle (32) defining said exit opening. The tube (34) comprises a flattened, smooth-walled tube (38) of a resilient plastics material, which tube normally retains its flattened cross-sectional shape (40) and resists the passage therethrough of any bulky object (42) which tends to deform and enlarge that shape. The tube parameters are chosen so as to limit the rate of descent of an object at the delivery end of the tube to a desired low value. A slotted transverse detachment member (18) at the upper end of the receptacle (14) facilitates detachment of an object from a suspension stalk (30) from which it hangs. <IMAGE>

Title: Flat cathode tube deflection waveforms
Inventor: MAYDEW PETER HOWARTH
IPC: H04N3/233
Filed: 1983-12-05
Abstract: The field scan waveform for an electrostatically deflected cathode ray tube having its electron gun placed to project a beam of electrons towards the screen from one side includes a component at line scan frequency to correct distortion of the raster due to the tube geometry. It is essential that the line scan frequency component is synchronized with the line scan deflection waveform which means that the flybacks must be described in the same time interval. A substantial saving in the power needed to produce the line scan waveform is obtained by arranging the field scan waveform to be such that the flyback portions of the line scan frequency component be performed in such directions as to reduce the field scan deflection. This enables the field scan amplifiers to use higher value collector resistances to achieve the charging and discharging of the circuit capacitances as required during the line flyback interval. The power consumption of the field scan amplifiers is thereby reduced. <IMAGE>

IPC: A01N3/00
Filed: 1983-12-06
Abstract: Heat treatment of bulbs for pest and disease control comprises placing the bulbs in a vessel 10 before evacuation of the vessel is effected by a pressure sensitive pump 18. Following evacuation, water vapor from a heated water bath 20 condenses on the bulbs and gives up its latent heat to raise them and accurately maintain them at the desired temperature for the necessary period. Following this, the vessel 10 may be further evacuated for vacuum drying of the bulbs before their removal from the vessel. <IMAGE>
